Ontology based description of an accessible learning object

Accessibility of e-learning systems to people with some disabilities is a current common problem. So, to create accessible e-learning platforms, we need a richer implementation of their pedagogical content. An ontological representation of learning object can be suitable way to encourage reusability, share and interoperability of learning object. The aim of this study is to present a design of an accessible learning object model using an ontological approach and compliant to IMS-AccessFor All v3.0 specification. The use of ontologies will define a semantic content structures and relationships between learning object, their components and their alternatives. We will use Protégé development tool.
